Seiko 5M42-0E60/69 4GM7-BA 20 mm rubber strap

Hello WRT members I started a project 4years ago printing straps for seiko model 5M42-0E69. This because the strap wasn’t produced anymore and i needed a strap for my father’s watch that come to my possession. I found someone who was willing to make a computer drawing and than he started printing and worked out well. To build up the metal caps you need to have some patience but it worked. 

He fiets printed a prototype in red. 

With some adjustments such as the heath off the printer he started to print them in the original color black. 

Sorry these are original SLQ003 straps!!!

This is a black printed strap

By the way the slq003 strap and the 5M42-0E60/69 strap are the same only the metal caps from the slq are a bit more robustly. 

Than I came to the idea to experiment with colors.

Great work, what material are you printing with?

The printing material is TPU my next step is to print them in a more rubber like TPU material and instead off using the computer drawing me gonna try a 3D scan from a original strap and see how that works out. 

This rubber like TPU is called 1301 but this is industrial material and a bit more expensive. 

Also thinking about printing straps for the 3m22-0d39 because these are also not produced anymore. 

If you have a watch in your collection and can’t buy or find a strap anymore find someone who has knowledge about 3D printing give it a try like I did.

Hello WRT members in my last post I mentioned about maybe try doing 3m22-0d39 straps. I got a request for this model so gave it a try. 
 

We kept the openings closed and we found out the strap would be much stronger. Gonna show you the result with the metal armor mounted on the strap. 

I fixed 2 3m22’s on request. 

A earlier project was a 5j22-0a70 with a broken rubber strap insert.
